I like the way Audacity implements markers; add one or more marker tracks.

Each marker track can be vertically positioned as desired. Each marker track extends the length of the timeline. Marker track content can be exported as a simple text file detailing marker location on the timeline (with precision down to the sample) and content inside each marker text box. If you want you can position one marker track next to the timeline and insert markers to identify each song part then additional marker tracks next to each audio track to insert comments and edit locations or just have one marker track to do it all.

Markers can be created by pressing F11 (?) When the focus is on a marker track or by a left mouse click inside a marker track. Each marker is a movable (click & drag) bullseye and has a unlimited text box. You can use your mouse or tab key to move between markers.

Finally, the software code is open source with a Creative Common license so the feature can be added with little effort or cost.
